Field Descri
p
tion
- underruns
Number of packets dropped because the output rate of the interface
exceeded the output queuing capability. This is a low-probability
hardware anomaly.
- buffer failures
Number of packets dropped because the transmit buffer of the
interface ran low.
aborts
Number of packets that failed to be transmitted, for example, because
of Ethernet collisions.
deferred
Number of frames that the interface deferred to transmit because of
detected collisions.
collisions
Number of frames that the interface stopped transmitting because
Ethernet collisions were detected during transmission.
late collisions
Number of frames that the interface deferred to transmit after
transmitting their first 512 bits, because of detected collisions.
lost carrier
Number of carrier losses during transmission. This counter applies to
serial WAN interfaces.
- no carrier
Number of times that the port failed to detect the carrier when
attempting to send frames. This counter applies to serial WAN
interfaces.
NOTE:
If an output field is not available, a hyphen (-) is displayed.
Table 4 Description on the possible physical states of a Layer 2 Ethernet interface
Field Descri
p
tion
UP The interface is physically up.
DOWN
The interface is physically down, because no physical connection exists
(possibly because the network cable is disconnected or faulty).
DOWN ( Administratively )
The interface is physically down because it was shut down with the shutdown
command. To restore its physical state, use the undo shutdown command.
DOWN ( Link-Aggregation
interface down )
The interface is physically down, because the aggregate interface
corresponding to the aggregation group to which it belongs was shut down
with the shutdown command.
DOWN ( OAM connection
failure )
The interface is physically down, because an OAM connection failed to be
established on it or the OAM connection is disconnected.
DOWN ( DLDP connection
failure )
The interface is physically down, because a DLDP connection failed to be
established on it or the DLDP connection is disconnected.
DOWN ( Loopback
detection-protected )
The interface is shut down because a loop is detected on it.
DOWN ( BPDU-protected ) The interface is shut down by the BPDU guard function.
DOWN ( Monitor-Link uplink
down )
The interface is physically down because the uplink of the monitor link group
to which it belongs is down.
